EXCLUSIVE:Jonathan Liebesman, who directed last year’s Teenage Mutant Ninja Turtles to a $485M worldwide box office take, is attached to direct Man At Arms for Basil Iwanyk’s Thunder Road Pictures. The project is a King Arthur story, but reminiscent of Clint Eastwood’s classic Western Unforgiven and follows Sir Lancelot as an older man who is bent on making amends after his love for Guinevere (and hers for him) ended up destroying Arthur’s Camelot. Great twist to the tried-and-true story.

Liebesman and Iwanyk worked together on Wrath Of The Titans which starred Sam Worthington, Liam Neeson and Rosamund Pike and grossed over $300 million worldwide. Man At Arms will be produced by Iwanyk, Adam Goldworm through Aperture Entertainment and Bryan Brucks (who is currently post on Scouts vs. Zombies at Paramount). Erica Lee will executive produce.

By coincidence, there is another King Arthur project out there written also by a competing Robin Hood writer. Joby Harold wrote Warner Bros.’ tale Knights Of The Round Table: King Arthur, which Guy Ritchie is directing. That one stars Charlie Hunnam, Jude Law, Djimon Hounsou and Eric Bana. Incidentally, Harold and Goldworm went to UCLA film school together.

However, Man At Arms is about Lancelot’s quest for redemption in his later years — based on an original idea by Brucks — and is less a post-modern invention of the of other.

Lott previously scripted/produced The Falling for Warner Bros. with Zac Efron to star. Together, he and Goodman also wrote Lore at Warner Bros. which has Dwayne ‘The Rock’ Johnson aboard.

Goldworm is currently in post on The Last Witch Hunter starring Vin Diesel and Michael Caine as well as Extraction starring Bruce Willis and Kellan Lutz. He is also executive producer for Bus 657 starring Robert De Niro.
